This is a quick reference cheat sheet for Docker. And you can find the most common Docker commands here.

#Getting Started

#Getting started

Create and run a container in background

$ docker run -d -p 80:80 docker/getting-started

  • -d - Run the container in detached mode
  • -p 80:80 - Map port 80 to port 80 in the container
  • docker/getting-started - The image to use

Create and run a container in foreground

$ docker run -it -p 8001:8080 --name my-nginx nginx

  • -it - Interactive bash mode
  • -p 8001:8080 - Map port 8001 to port 8080 in the container
  • --name my-nginx - Specify a name
  • nginx - The image to use
